zstd significantly reduces cluster compression time.
It provides better compression performance maintaining
the same level of the compression ratio in comparison with
zlib, which, at the moment, is the only compression
method available.
The performance test results:
Test compresses and decompresses qemu qcow2 image with just
installed rhel-7.6 guest.
Image cluster size: 64K. Image on disk size: 2.2G
The test was conducted with brd disk to reduce the influence
of disk subsystem to the test results.
The results is given in seconds.
compress cmd:
time ./qemu-img convert -O qcow2 -c -o compression_type=[zlib|zstd]

Currently "cf-core.xml" is sent to GDB when using any m68k flavor. Thing is
it uses the "org.gnu.gdb.coldfire.core" feature name and gdb 8.3 then expects
a coldfire FPU instead of the default m68881 FPU.
This is not OK because the m68881 floats registers are 96 bits wide so it
crashes GDB with the following error message:

The original commit (40d6444e91) said:
"Non-x86 are not changed, as they require TCG changes"

The comment in tcg-runtime-gvec.c about CONFIG_VECTOR16 says that
tcg-op-gvec.c has eliminated size 8 vectors, and only passes on
multiples of 16. This may have been true of the first few operations,
but is not true of all operations.
In particular, multiply, shift by scalar, and compare of 8- and 16-bit
elements are not expanded inline if host vector operations are not
supported.
For an x86_64 host that does not support AVX, this means that we will
fall back to the helper, which will attempt to use SSE instructions,
which will SEGV on an invalid 8-byte aligned memory operation.
This patch simply removes the CONFIG_VECTOR16 code and configuration
without further simplification.

glibc and Linux-provided headers are known to generate macro
redefinition warnings when used together. For example:
<linux/mman.h> and <sys/mman.h> duplicate some macro definitions.
We normally never see those warnings because GCC suppresses
warnings generated by system headers. We carry our own copy of
Linux header files, though, and this makes those warnings not be
suppressed when glibc headers are included before Linux headers
(e.g. if <sys/mman.h> is included before <linux/mman.h>).
Use -isystem instead of -I for linux-headers. This makes the
compiler treat our linux-headers directory the same way it treats
system-provided Linux headers, and suppress warnings generated by
them.

The Simple Authentication and Security Layer (SASL) library
re-defines the struct iovec on Win32 [*]. QEMU also re-defines
it in "qemu/osdep.h". The two definitions then clash on a MinGW
build.
We can avoid the SASL definition by defining STRUCT_IOVEC_DEFINED.
Since QEMU already defines 'struct iovec' if it is missing, add
the definition to vnc_sasl_cflags to avoid SASL re-defining it.

On upgrades the old .so files usually are replaced. But on the other
hand since a qemu process represents a guest instance it is usually kept
around.
That makes late addition of dynamic features e.g. 'hot-attach of a ceph
disk' fail by trying to load a new version of e.f. block-rbd.so into an
old still running qemu binary.
This adds a fallback to also load modules from a versioned directory in the
temporary /var/run path. That way qemu is providing a way for packaging
to store modules of an upgraded qemu package as needed until the next reboot.
An example how that can then be used in packaging can be seen in:

The recent Linux io_uring API has several advantages over ppoll(2) and
epoll(2). Details are given in the source code.
Add an io_uring implementation and make it the default on Linux.
Performance is the same as with epoll(7) but later patches add
optimizations that take advantage of io_uring.
It is necessary to change how aio_set_fd_handler() deals with deleting
AioHandlers since removing monitored file descriptors is asynchronous in
io_uring. fdmon_io_uring_remove() marks the AioHandler deleted and
aio_set_fd_handler() will let it handle deletion in that case.

This adds a new binary qemu-storage-daemon that doesn't yet do more than
some typical initialisation for tools and parsing the basic command
options --version, --help and --trace.
Even though this doesn't add any options yet that create things (like
--object or --blockdev), already document that we're planning to process
them in the order they are given on the command line rather than trying
(and failing, like vl.c) to resolve dependencies between options
automatically.

Currently configure's has_sphinx_build() check simply runs a dummy
sphinx-build and either passes or fails. This means that "no
sphinx-build at all" and "sphinx-build exists but is too old" are
both reported the same way.
Further, we want to assume that all the Python we write is running
with at least Python 3.5; configure checks that for our scripts, but
Sphinx extensions run with whatever Python version sphinx-build
itself is using.
Add a check to our conf.py which makes sphinx-build fail if it would
be running our extensions with an old Python, and handle this
in configure so we can report failure helpfully to the user.
This will mean that configure --enable-docs will fail like this
if the sphinx-build provided is not suitable:
Warning: sphinx-build exists but it is either too old or uses too old a Python version
ERROR: User requested feature docs
configure was not able to find it.
Install texinfo, Perl/perl-podlators and a Python 3 version of python-sphinx
(As usual, the default is to simply not build the docs, as we would
if sphinx-build wasn't present at all.)

Some of the CFLAGS that are discovered during configure, for example
compiler warnings, are being included on the linker command line because
QEMU_CFLAGS is added to it. Other flags, such as the -m32, appear twice
because they are included in both QEMU_CFLAGS and LDFLAGS. All this
leads to confusion with respect to what goes in which Makefile variables
(and we have plenty).
So, introduce QEMU_LDFLAGS for flags discovered by configure, following
the lead of QEMU_CFLAGS, and stop adding to it:
1) options that are already in CFLAGS, for example "-g"
2) duplicate options
At the same time, options that _are_ needed by both compiler and linker
must now be added to both QEMU_CFLAGS and QEMU_LDFLAGS, which is clearer.
This is mostly -fsanitize options. For now, --extra-cflags has this behavior
(but --extra-cxxflags does not).
Meson will not include CFLAGS on the linker command line, do the same in our
build system as well.

It's been deprecated since QEMU v3.1. We've explicitly asked in the
deprecation message that people should speak up on qemu-devel in case
they are still actively using the bluetooth part of QEMU, but nobody
ever replied that they are really still using it.
I've tried it on my own to use this bluetooth subsystem for one of my
guests, but I was also not able to get it running anymore: When I was
trying to pass-through a real bluetooth device, either the guest did
not see the device at all, or the guest crashed.
Even worse for the emulated device: When running
qemu-system-x86_64 -bt device:keyboard
QEMU crashes once you hit a key.
So it seems like the bluetooth stack is not only neglected, it is
completely bitrotten, as far as I can tell. The only attention that
this code got during the past years were some CVEs that have been
spotted there. So this code is a burden for the developers, without
any real benefit anymore. Time to remove it.
Note: hw/bt/Kconfig only gets cleared but not removed here yet.
Otherwise there is a problem with the *-softmmu/config-devices.mak.d
dependency files - they still contain a reference to this file which
gets evaluated first on some build hosts, before the file gets
properly recreated. To avoid breaking these builders, we still need
the file around for some time. It will get removed in a couple of
weeks instead.

Libgcrypt 1.8.0 added support for the XTS mode. Use this because long
term we wish to delete QEMU's XTS impl to avoid carrying private crypto
algorithm impls.
As an added benefit, using this improves performance from 531 MB/sec to
670 MB/sec, since we are avoiding several layers of function call
indirection.
This is even more noticable with the gcrypt builds in Fedora or RHEL-8
which have a non-upstream patch for FIPS mode which does mutex locking.
This is catastrophic for encryption performance with small block sizes,
meaning this patch improves encryption from 240 MB/sec to 670 MB/sec.

- enhance the output so docker is no longer just yes
In the configure script we can at least start cleaning up the
detecting and naming of variables. To avoid too much churn the
conversion of the various make DOCKER_foo variables has been left for
future clean-ups.

The current approach to capture the Python version is fragile, as it
was demonstrated by a very specific build of Python 3 on Fedora 29
that, under non-interactive shells would print multiline version
information.
The (badly) stripped version output would be sent to config-host.mak,
producing bad syntax and rendering the makefiles unusable. Now, the
Python versions is printed by configure, but only a simple (and better
controlled variable) indicating whether the build system is using
Python 2 is kept on config-host.mak.

glib: bump min required glib library version to 2.48
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
Per supported platforms doc[1], the various min glib on relevant distros is:
RHEL-8: 2.56.1
RHEL-7: 2.50.3
Debian (Buster): 2.58.3
Debian (Stretch): 2.50.3
OpenBSD (Ports): 2.58.3
FreeBSD (Ports): 2.56.3
OpenSUSE Leap 15: 2.54.3
SLE12-SP2: 2.48.2
Ubuntu (Xenial): 2.48.0
macOS (Homebrew): 2.56.0
This suggests that a minimum glib of 2.48 is a reasonable target.

glib: bump min required glib library version to 2.40
This will result in us dropping support for Debian Jessie and
Ubuntu 14.04.
As per the commit message 14.04 was already outside our list
of supported build platforms and an exception was only made
because one of the build hosts used during merge testing was
stuck on 14.04.
Debian Jessie is justified to drop because we only aim to
support at most 2 major versions of Debian at any time. This
means Buster and Stretch at this time.
The g_strv_contains compat code is dropped as this API is
present since 2.44
The g_assert_cmpmem compat code is dropped as this API is
present since 2.46

Only the emulators link to code that uses capstone, so adding it to the
global LIBs places undesirable dependancies on other binaries, in
particular the tools.
There is no variable that covers both user emulation and machine
emulation, so add a new "$libs_cpu" for this purpose.
In particular this removes the 8 MB capstone dep from the things
qemu-img links against, allowing for a more minimal installation
in scenarios that don't want system emulators installed.

We make a few sub-directories recursively, in particular
$(TARGET_DIRS).
For goal "all", we do it the nice way: "all" has a prerequisite
subdir-T for each T in $(TARGET_DIRS), and T's recipe runs make
recursively. Behaves nicely with -j and -k.
For other goals such as "clean" and "install", the recipe runs make
recursively in a for loop. Ignores -j and -k.
The next commit will fix that for "clean" and "install". This commit
prepares the ground by renaming the targets we use for "all" to
include the goal for the sub-make. This will permit reusing them for
goals other than "all".
Targets subdir-T for T in $(TARGET_DIRS) run "make all" in T. Rename
to T/all, and declare phony.
Targets romsubdir-R for R in $(ROMS) run "make" in pc-bios/R. Default
goal is "all" for all R. Rename to pc-bios/R/all, and declare phony.
The remainder are renamed just for consistency.
Target subdir-dtc runs "make libbft/libfdt.a" in dtc. Rename to
dtc/all, and declare phony.
Target subdir-capstone runs make $(BUILD_DIR)/capstone/$(LIBCAPSTONE)
in $(SRC_PATH)/capstone. Rename to capstone/all, and declare phony.
Target subdir-slirp runs "make" in $(SRC_PATH)/slirp. Default goal is
all, which builds $(BUILD_DIR)/libslirp.a. Rename to slirp/all, and
declare phony.

The configure script breaks when the qemu source directory is in a path
containing white spaces, in particular the list of targets is not
correctly generated when calling "./configure --help" because of how the
default_target_list variable is built.
In addition to that, *building* qemu from a directory with spaces breaks
some assumptions in the Makefiles, even if the original source path does
not contain spaces like in the case of an out-of-tree build, or when
symlinks are involved.
To avoid these issues, refuse to run the configure script and the
Makefile if there are spaces or colons in the source path or the build
path, taking as inspiration what the kbuild system in linux does.

Rewrite the implementation of the ssh block driver to use libssh instead
of libssh2. The libssh library has various advantages over libssh2:
- easier API for authentication (for example for using ssh-agent)
- easier API for known_hosts handling
- supports newer types of keys in known_hosts
Use APIs/features available in libssh 0.8 conditionally, to support
older versions (which are not recommended though).
Adjust the iotest 207 according to the different error message, and to
find the default key type for localhost (to properly compare the

For user-only, we require only the random number bits of the
crypto subsystem. Rename crypto-aes-obj-y to crypto-user-obj-y,
and add the random number objects, plus init.o to handle any
extra stuff the crypto library requires.
Move the crypto libraries from libs_softmmu and libs_tools to
LIBS, so that they are universally used.

The Makefile tries to include device Kconfig dependencies via
-include $(SUBDIR_DEVICES_MAK_DEP)
and thus expects files that match *-softmmu/config-devices.mak.d ...
however, the minikconf script currently generates files a la
"*-softmmu-config.devices.mak.d" instead, so the dependency files
simply got ignored so far. For example, after a "touch hw/arm/Kconfig",
the arm-softmmu/config-devices.mak file is currently not re-generated.
Fix it by putting the dependency files in the *-softmmu folders now.

The pam test generates a warning on Fedora 29 with -O3 compilation

pam_start must be non-NULL. Change it to use the same 0 initialised

Unless overridden via an env var or configure arg, QEMU will only look
for the 'python' binary in $PATH. This is unhelpful on distros which
are only shipping Python 3.x (eg Fedora) in their default install as,
if they comply with PEP 394, the bare 'python' binary won't exist.
This changes configure so that by default it will search for all three
common python binaries, preferring to find Python 3.x versions.

When running "make" in a build directory from the pre-Kconfig merge time,
the build process currently fails with:
make: *** No rule to make target `.../default-configs/pci.mak',
needed by `aarch64-softmmu/config-devices.mak'. Stop.
To make sure that this problem at least goes away when the user runs
"configure" (or "sh config.status") again, we have to make sure that
we re-generate the .mak.d files. Thus remove the old stale files
while running the configure script.
